虎求百兽而食之，得狐。狐曰：“子无敢食我也！天帝使我长百兽，今子食我，是逆天帝命也。子以我为不信，吾为子先行，子随我后，观百兽之见我而不敢不走乎？”虎以为然，故遂与之行，兽见之皆走，虎不知兽畏己而走也，以为畏狐也。（《战国策》）

    A tiger went about in search of other weaker animals for food.Once in his hunting,he happened to find a fox."You won't dare to eat me,"said the fox,"as I am head of all animals appointed by God.It is against the will of God,if you eat me now.In case you don't believe what I say,let us go together.You just follow me as I go ahead to see if there is any animal that does not run away when I pass." The tiger agreed and went with the other.Certainly he saw all the animals run away on seeing the fox.He thought they were afraid of the fox without knowing it was he himself that they feared.
